I don't know if Tendril would stay around to even fight Bast, Mace, and Namah. His job was to kill Lilith, he probably would run away and retreat. Unless he can still animate a huge skeleton like in that now non-cannon minicomic, he is not built for direct combat.

If Tendril lays his eyes on Lilith again, he's gonna go ballistic. I bet that in his mind, if he sees one of Lilith's friends or anyone that she knows of, he would tell them something similar to these things.....
